General Motors Is Working on Plan
To Replace Aging Michigan Plant

DETROIT -- General Motors Corp. is working on plans to build a car factory costing as much as $1 billion near Lansing, Mich., its second new plant in the region.

The proposed factory, which hasn't yet won approval from GM's board, would replace an aging factory complex in the city. The new plant would build GM's next generation of midsize cars, known by the code name Epsilon, according to people familiar with the plans.
